This impressive publication presents the proceedings of the 1993 Toronto Stormwater and Water Quality Modelling meeting. The number of papers in the book has been substantially increased and, for the first time, the contributions have been peer reviewed for novelty, accuracy, readability, and relevance. Chapters are arranged in five sections: ecosystem impacts, water quality modelling, new methods and modelling, data management, and current practice. The appendices are valuable research aids, with a detailed index, a substantial glossary encompassing the entire discipline, lists of acronyms, models, and abbreviations, and a complete list of authors cited in the book. The editor also provides a classification of the 485 papers of the 11-year series of conferences held at the University of Kentucky at Louisville.

The latest book in the popular series demonstrates state-of-the-art methods, models, and techniques for water quality management. This book includes a CD-ROM that collects hundreds of hard-to-find literature citations from the gray literature.

The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

New Techniques for Modelling the Management of Stormwater Quality Impacts is a unique volume devoted to discussing new developments in modeling, best management practices (BMPs), information management, user interfacing, and instrumentation for reducing the impacts of urbanization on aquatic ecosystems. The book is divided into three sections: ecosystems and environmental modeling contexts; best management practices, including real-time control; and applications of geographical information systems (GIS). Specific topics addressed include the need to move from a regulatory basis for system management to a process-based management system, the use of remote sensing to divide a catchment into six different hydrologic response classes to compute floods, instrumentation, data acquisition, real-time control, aspects of stormwater detention ponds, and methods for using GIS. Detailed indexes, lists of acronyms, programs and models, and a full glossary are provided at the end of the book. New Techniques for Modelling the Management of Stormwater Quality Impacts will interest professional engineers in municipal and environmental engineering, consultants, researchers in civil engineering, hydrological engineers, hydraulics engineers, environmental policy makers, and students.

Hydroinformatics systems are systems that combine computational hydraulic modelling with information systems (including knowledge-based systems). They are gaining rapid acceptance in the areas of environmental planning, design and management. The present book focuses exclusively on sewage systems, starting with their planning and then going on to discuss their design, operation and rehabilitation. The very experienced authors discuss business and information needs in the management of urban drainage, tools for collecting and archiving such data, and their use in modelling catchment hydrology, sewer systems hydraulics, wastewater quality, wastewater treatment plant operation, and receiving waters. The control and operation of sewer systems in real time is described, followed by a discussion of their maintenance and rehabilitation. Intelligent decision support systems for managing the urban drainage business process are presented. Audience: Researchers into sewer design, municipal engineers, planners and managers interested in an innovative approach to all aspects of the planning, design and operation of sewer systems.

The 20th century's automobile-inspired land use changes brought about tremendous transformations in how stormwater moves across the modern urban land-scape. Streets and parking areas in the average urban family's neighborhood now exceed the amount of land devoted to living space. Add parking, office and commercial space, and it's easy to understand how modern cities have experienced a three-fold increase in impervious areas. Traditional wet weather collection systems removed stormwater from urban areas as quickly as possible, often transferring problems downstream. Innovative Urban WetWeather Flow Management Systems does two things: It considers the physical, chemical, and biological characteristics of urban runoff; then describes innovative methods for improving wet weather flow (WWF) management systems. The result of extensive research, Innovative Urban Wet-Weather Flow Manage-ment Systems looks most at how to handle runoff in developments of the 21st century: the confl icting objectives of providing drainage while decreasing stormwater pollutant discharges; the impact of urban WWF on surface and groundwater, such as smaller urban stream channels scoured by high peak flows; sediment transport and the toxic effects of WWF on aquatic organisms; the effectiveness of WWF controls-including design guidelines and source and downstream controls-are an important issue. Innovative Urban Wet-Weather Flow Management Systems looks at how source controls like biofi ltration, created through simple grading, may work in newly developing areas, while critical source areas like an auto service facilities, may need more extensive treatment strategies. Focusing WWF treatment on intensively used areas, such as the 20 percent of streets that handle the bulk of the traffic, and under utilized parking areas is also considered. Developing a more integrated water supply system-collecting, treating, and disposing of wastewater, and handling urban WWF-requires innovative methods, such as a neighborhood-scale system that would recycle treated wastewater and storm water for lawn watering and toilet flushing, or use treated roof runoff for potable purposes.
